10 safe and natural remedies to repel cockroaches

Want to get rid of those critters without harming your family's health?

With the warm, moist environment that comes with living in the tropics, also comes an army of bugs — cockroaches included. So we zap those pesky bugs with anything we can find, usually insecticides. We certainly don’t want roaches crawling around our homes. But at the same time, do we really want to expose our kids to the poison of insecticides? Here are some clever ways to repel cockroaches naturally.

Repel Cockroaches Naturally with Ingredients Found in Your Kitchen!

There are some ingredients in your kitchen that can be used to trap, repel, and kill those pesky critters at your home. All you need to do is to mix them up and place it where cockroaches usually hide.

1. Essential Oils

Did you know that cockroaches hate the smell of peppermint, lavender, eucalyptus, and tea tree oils? That is because it disrupts and masks the scent trails which cockroaches use to hunt for their food. Roaches die when they are exposed to higher concentrations of essential oils, particularly peppermint oil.

Use essential oils to repel cockroaches naturally by putting a few drops of peppermint oil on a cotton ball, and wiping down places where cockroaches usually hide or enter your home.

You can also make a spray by mixing 15 drops of peppermint oil and 10 ounces of water in a spray bottle. Mix thoroughly and spray in possible entry points and dark areas.

2. Borax

Borax is an effective natural cleaner and a safer alternative to many conventional cleaners. It contains boric acid that when ingested by cockroaches, destroys the cellular lining of their guts.

To kill roaches with borax, mix two tablespoons of borax and two cups of sugar in a liter of water and pour the mixture into a spray bottle. You may add two to three drops of peppermint oil in the mixture too. Mix thoroughly and spray in suspected areas. You can also use it to repel ants too!

3. Diatomaceous Earth

This is a non-toxic substance that can be use to kill and repel cockroaches naturally. When the roach comes in contact with this substance through ingestion, its body dries out, killing it eventually.

To use this effectively, mix diatomaceous earth with some sugar to attract cockroaches. Sprinkle a thin layer of it around the entryways of your home or anywhere you think roaches hide. Make sure you re-apply this remedy daily as it tends to absorb moisture from the atmosphere.

4. Baking Soda

Baking soda is a leavening agent used in baking cakes and can also be use as an effective home cleaning remedy.

It can also kill roaches. Just mix one part baking soda with one part of sugar. The sugar attracts the roaches and the baking soda kills them. Place the mixture in small bowls or jar lids or sprinkle it in corners and baseboards.

6. Catnip

Catnip has been widely used as a natural insect repellent for centuries. It contains Nepetalactone, an active chemical that repels insects without harming humans and pets. It is one of the most effective remedy to repel cockroaches naturally.

To use this, boil catnip leaves for 10 minutes and let it cool before transferring the mixture to a spray bottle. Spray it around the house.

10. Silica Gels

Silica Gels or Desiccants are commonly seen as beads in a small paper packet that control the humidity of goods to avoid spoilage. They absorb moisture and dry out anything that comes in direct contact. When roaches come in contact with the substance, the gel dries out their body, killing them eventually.

You can use desiccants effectively by mixing the beads with sugar and sprinkling the mixture around the house, away from children and pets.

How To Prevent Cockroaches from Coming Back

Relying only on natural insecticides is not the solution to a cockroach infestation in your home. Roaches love warm, humid places where they can find food and breed. And prevention is key to ensure roaches stay away for good.

When you see one or two roaches freely roaming in your home, you shouldn’t take it lightly. It probably means there are many others running about in hidden corners of your home.

Cockroaches can transmit bacteria and spread diseases to your family. Here are tips to prevent them from coming back to your home:

Keep your house clean. Clean the dishes straight away after meals and clean up spills and crumbs to limit food for cockroaches. Sweep the floor and mop it regularly to disrupt scent trails of food.

Take out the trash regularly and keep the trash bins closed at all times. Cockroaches often lurk in places where they can find food, and our garbage is one of their favourite spots.

Store food in tightly-sealed containers. This will prevent cockroaches and other insects from contaminating your food.

Cover all the cracks and crevices around your house. You can use paint or cement to block entry points of insects to your house.
